Technical field

This application relates to the field of computers, and in particular to a method for measuring human body temperature, electronic equipment and computer-readable storage media.

Background technique

In clinical practice, body temperature refers to the core temperature of the human body. As shown in Figure 1, core body temperature (CBT), also known as core body temperature or body temperature, refers to the temperature of the thoracic cavity, the inside of the abdominal cavity, and the central nervous system. As shown in Figure 1, the difference between body temperature in a cold environment and a warm environment is small, generally relatively constant, and the fluctuation range is small. Body temperature is one of the four vital signs of the human body. Many physiological activities of the human body, such as hormone regulation, immune response, natural rhythm, etc., are accompanied by changes in body temperature. Therefore, body temperature measurement results, especially continuous measurement results It is of great significance to the application of women's menstrual cycle management, biological rhythm regulation, and chronic disease management.

As shown in Figure 1, body temperature is the temperature inside the human body, which is inconvenient to measure. The rectal temperature, oral temperature (under the tongue), tympanic membrane temperature (in the ear) are closest to body temperature, and the corresponding relationship between axillary temperature, forehead temperature, chest temperature and body temperature is relatively stable. Therefore, in actual measurement scenarios, it is usually in the armpit , Under the tongue (in the mouth), tympanic membrane (in the ear), underarms, forehead, chest and other locations to measure temperature, and the measured temperature as body temperature. Existing body temperature measurement methods are difficult to balance measurement accuracy and convenience, and the user experience is poor.

Summary of the invention

This application provides a human body temperature measurement method, electronic equipment, and computer-readable storage medium, in order to improve the comfort and convenience of the human body temperature measurement process, and improve the measurement accuracy.

In the first aspect, this application provides a method for measuring human body temperature, which is applied to a wrist wearable device, such as a smart watch or a smart bracelet.

In the embodiment of the present application, the first temperature can be measured by the first temperature sensor, and the second temperature can be measured by the second temperature sensor. Within, such as simultaneous measurement or the data of the last measurement. Among them, the first temperature sensor is used to measure the temperature of the user’s forehead, for example, the temperature sensor 11 provided on the front of the smart watch; and the second temperature sensor is used to measure the temperature of the user’s wrist, for example, the temperature provided on the back of the smart watch Sensor 13 or temperature sensor 14. In this case, when the user's body temperature measurement result is displayed on the display screen, the third temperature can be displayed. Then, when the smart watch subsequently uses the second temperature sensor to measure the fourth temperature, and the fourth temperature is the same as the second temperature, the third temperature can be displayed on the display screen. At this time, there is no need to repeatedly measure the body temperature of the user's forehead, and the user's human body temperature can be automatically measured, and the comfort is higher; moreover, because the temperature of the forehead is closer to the core temperature of the human body, the temperature of the forehead is adjusted After the second temperature is corrected, the third temperature is displayed, which is also helpful to improve the measurement accuracy.

In an embodiment of the present application, the third temperature may be the first temperature. For example, in the embodiment shown in FIG. 22, the first temperature is the forehead temperature Tf measured by the temperature sensor 11, and the second temperature is the skin surface temperature Ts measured by the temperature sensor 13. In this way, only the value of Ts to Tf needs to be established. The corresponding relationship is Tf=f(Ts). Then, when the subsequent temperature sensor 13 measures the same Ts value again, it can correspond to the same Tf and display the Tf value on the display screen. For another example, in the embodiment shown in FIG. 24, the first temperature is the forehead temperature Tf measured by the temperature sensor 11, and the second temperature is the deep skin temperature Td measured by the temperature sensor 14. In this way, it is only necessary to establish Td to Tf. The corresponding relationship of Tf=f(Td), then, when the subsequent temperature sensor 14 measures the same Td value again, it can correspond to the same Tf and display the Tf value on the display screen.

In another embodiment of the present application, the third temperature may also be associated with the first temperature and the second temperature. Still take the embodiment shown in FIG. 22 and FIG. 24 as an example. In the embodiment shown in FIG. 22, the third temperature can be obtained by looking up a table, for example, by querying the correspondence table between Tf, Ts and T to obtain the first temperature (Tf) and the second temperature ( At this time, it is the third temperature (T) corresponding to Ts); or, it can also be obtained by weighting Tf and Ts, for example, T=w1*Tf+w2*Ts. In another embodiment, as shown in FIG. 24, the third temperature can be obtained by looking up a table, for example, querying the correspondence table between Tf, Td and T to obtain the first temperature (Tf) and The third temperature (T) corresponding to the second temperature (Td at this time); or, it can also be obtained by weighting Tf and Td, for example, T=w5*Tf+w6*Td.

In addition, the embodiment of the present application may further consider the influence of the ambient temperature on the measured temperature, so that the ambient temperature is used to correct the measured temperature. At this time, the third temperature is associated with the fifth temperature, and the fifth temperature is obtained after correcting the first temperature by using the ambient temperature. For example, as shown in FIG. 15, FIG. 21, FIG. 23, FIG. 25, and FIG. 26, the fifth temperature can be expressed as the body temperature Tc at the forehead, which is obtained by correcting the forehead temperature Tf with the ambient temperature Te.

In this case, the third temperature may be the fifth temperature. That is, the value of Tc is displayed on the display screen. For example, in the embodiment shown in FIG. 23, after the forehead temperature Tf is corrected by the ambient temperature Te, Tc is obtained. In this way, the corresponding relationship Tc=f(Ts) between Ts and Tc is established, then the subsequent temperature sensor 13 When the same Ts value is measured again, it can correspond to the same Tc, and the Tc value will be displayed on the display. For another example, in another example, as shown in FIG. 25 or FIG. 26, after the forehead temperature Tf is corrected by the ambient temperature Te, Tc is obtained. In this way, the corresponding relationship Tc=f(Td) between Td and Tc is established. , Then, when the second temperature sensor subsequently measures the same Td value again, it can correspond to the same Td and display the Tc value on the display screen.

In the foregoing embodiment, the ambient temperature may be measured by the third temperature sensor. In this case, the third temperature sensor may be provided in the smart watch or in another electronic device. Alternatively, the ambient temperature can also be obtained through network methods. For example, when a smart watch is connected to a mobile phone via Bluetooth, it can receive the ambient temperature recorded in the mobile phone via Bluetooth.

As mentioned above, in the embodiment of the present application, the second temperature sensor may be used to measure the deep skin temperature of the user's wrist. At this time, the second temperature sensor may be the heat flux sensor 14.

Or, in another embodiment, the second temperature sensor is used to measure the skin surface temperature of the user's wrist. At this time, the second temperature sensor may be the surface temperature sensor 13.

In this case, the embodiment of the present application also provides an implementation manner: refer to the embodiment shown in FIG. 26, in this embodiment, the first heat flux can also be measured by the heat flux sensor 14; The heat flux sensor is used to measure the heat flux between the skin surface temperature and the skin deep layer temperature; the difference between the measurement time of the first heat flux and the second temperature is within a preset second time period. In other words, when the user actively measures the body temperature of the forehead, the heat flux sensor 14 can also measure the heat flux value, thus participating in the calculation together with the second temperature (the skin surface temperature Ts measured by the temperature sensor 13 at this time). , Through the mapping relationship between Tc and Td (in another embodiment, the mapping relationship between Tf and Td may also be used) to obtain the user's body temperature. Therefore, in this embodiment, when the user's body temperature is automatically measured by the wrist wearable device later, in addition to measuring the fourth temperature by the second sensor, the second heat flux can also be measured by the heat flux sensor. The difference between the measurement time of the second heat flux and the fourth temperature is within the second time period; thus, when the fourth temperature is the same as the second temperature, and the first heat When the flux is the same as the second heat flux, the third temperature is displayed on the display screen.

In addition, in the embodiment of the present application, when the wrist wearable device automatically measures the user's body temperature, if the measured fourth temperature is different from the second temperature, the difference between the second temperature and the first temperature can be obtained. Correspondence between. Thus, according to the corresponding relationship, a sixth temperature corresponding to the fourth temperature is acquired, and the sixth temperature is displayed on the display screen.

In this embodiment, the corresponding relationship may be stored in a preset storage location, and the corresponding relationship may be preset in the smart watch by the developer in advance, or may be established by the smart watch. Therefore, in a possible embodiment, if the corresponding relationship is established by the smart watch, it can be realized by data accumulated in multiple measurements. That is, a plurality of the first temperatures and a plurality of the second temperatures are used to establish the corresponding relationship; and the corresponding relationship is stored in a preset storage location.

Wherein, a threshold value can also be preset, and when the number of first temperatures reaches the preset threshold value, the corresponding relationship is established. That is, after a certain amount of data is accumulated, the corresponding relationship is established based on the data, which is beneficial to improve the accuracy of the corresponding relationship, and further, is beneficial to improve the accuracy of the user's body temperature finally displayed on the display screen. For example, in the example shown in FIG. 22, when the number of times the user actively measures body temperature reaches K1 times, such as 20 times, the Tf collected by the infrared thermopile sensor 11 during these 20 measurements and the Ts corresponding to Tf can be used to Establish the mapping function Tf=f(Ts).

After the corresponding relationship is established, the smart watch can also update and maintain the corresponding relationship. In an embodiment, after the corresponding relationship is established, when the number of the received first temperatures reaches a preset number threshold, the corresponding relationship is updated. For example, in the embodiment shown in FIG. 22, after the mapping function is established, the user actively measures the body temperature M1 times, for example 30 times, using these 30 Tf data and the Ts data corresponding to Tf to re-determine the difference between Tf and Ts. The mapping function between, realize the update of the mapping function. For another example, in the embodiment shown in FIG. 24, when the number of active measurements by the user reaches M3 times, the processor of the smart watch can also use the measurement data stored in the preset storage location to map between Tf and Td. The function is updated to make the third corresponding relationship closer to the user's recent body temperature state, which is beneficial to improve the measurement accuracy of the body temperature T.

In the embodiment of the present application, the first temperature sensor is used to measure the temperature of the user's forehead, and the first temperature sensor may measure the first temperature and output the first temperature in response to receiving a body temperature measurement instruction triggered by the user. For example, in the embodiment shown in FIG. 5, the temperature sensor 11 may start working after the user clicks the virtual button of "body temperature measurement". In this way, the forehead temperature can be measured when the user raises the wrist so that the temperature sensor 11 is aimed at the user's forehead.

The second temperature sensor measures temperature data according to a preset period or time, and outputs the temperature data. That is, the second temperature sensor can automatically measure the temperature, and can also realize the function of automatically measuring the user's body temperature. In addition, in another embodiment, when the first temperature sensor measures the first temperature, the second temperature sensor measures the second temperature. In this way, it can be ensured that the first temperature is close to the second temperature. In specific implementation, the first temperature sensor 11 may notify the second temperature sensor to work through direct or indirect communication; or, the second temperature sensor also starts to work in response to receiving a body temperature measurement instruction triggered by the user.

In the embodiment of the present application, the electronic device 100 may be used to measure the body temperature of the user. Specifically, the electronic device 100 may be: a smart watch, a smart bracelet, a smart earphone, a smart glasses, a mobile phone, and other scientific wearable smart devices (for example, a chest strap, an armband, etc.), etc., which are not limited in this application.

Now, taking the electronic device 100 as a smart watch as an example, the process of measuring the user's body temperature by the electronic device 100 will be described.

As shown in Figure 3, the smart watch can be worn on the user's wrist. In this way, the body temperature measurement can be completed while the user wears the smart watch. Compared with the measurement method in which the temperature measurement accessory is attached to the user, the adhesive method avoids the possibility of the user's skin allergies, and the comfort is higher.

Exemplarily, FIG. 4 shows a schematic diagram of a smart watch measuring the body temperature of a user. As shown in Figure 4, when the user wears the watch, the user can do any action without restriction. When the user needs to measure the body temperature, assuming that the forehead temperature is measured, the user can raise his hand to aim the smart watch at the user’s forehead for a short period of time, such as 1 second, the smart watch can measure the user’s forehead temperature and display the body temperature measurement result. Among them, the body temperature measurement result may be the measured forehead temperature, or may also be the temperature after processing the forehead temperature. For example, the measured forehead temperature is 36.8°C, while the displayed user's body temperature may be 36.9°C. The method of obtaining body temperature measurement results will be described in detail later. In addition, the body temperature measurement result can be displayed on the display screen of the smart watch, or on a mobile phone (or other electronic device) connected to the smart watch, as will be described in detail later. In this way, the user only needs to make a simple gesture of raising his hand, and the smart watch can automatically measure the user's body temperature, which is convenient and quick to operate.

It can be understood that, in the manner shown in FIG. 4, the user can also aim the smart watch at different parts of the human body through different actions to measure body temperature according to different parts of the human body. For example, the user can point the smart watch at the ear to measure the tympanic membrane temperature and display the temperature measurement result. For another example, the user can also point the smart watch at the oral cavity to measure the oral cavity temperature and display the body temperature measurement result. For another example, the user can also point the smart watch at the armpit to measure the temperature of the armpit, and then display the body temperature measurement result. Not exhaustively. The body part measured by the user raising his hand is associated with the body temperature measurement result, which will be described in detail later.

For ease of understanding, the technical solution provided by the implementation of the present application will be explained by taking the user raising his hand to measure the temperature of the forehead as an example.

In an embodiment, FIG. 5 shows a schematic diagram of a user interacting with a smart watch to measure body temperature. As shown in Fig. 5, on the front of the smart watch, a temperature sensor 11 and a display 15 are provided. It can be understood that the temperature sensor 11 may be one of the temperature sensors 180J shown in FIG. 2, and the display screen 15 may be specifically the display screen 194 shown in FIG. 2.

The temperature sensor 11 is arranged on the front of the smart watch. When the user raises the wrist and the smart watch is aimed at the user's forehead, the temperature sensor 11 is also aimed at the user's forehead. In this way, the temperature sensor 11 can measure the temperature of the forehead when the user raises his hand, thus, The current body temperature of the user can be displayed on the display 15 of the smart watch.

In a specific implementation, the temperature sensor 11 may be a non-contact temperature sensor. For example, the temperature sensor 11 may specifically be an infrared thermopile sensor. Among them, the infrared thermopile sensor is made using the principle that the energy radiated from the human body changes with temperature. Specifically, in nature, any object above absolute zero will radiate energy at a certain wavelength, but the wavelength of the energy radiated outward is different. For example, the human body temperature is 37°C, and the infrared radiation wavelength is generally 9-10μm. The infrared thermopile sensor converts the absorbed infrared radiation into heat (temperature), and converts it into an electronic signal to output and display. Therefore, the infrared thermopile sensor 11 can be designed on the front of the smart watch. In this way, as shown in Figure 4, the user only needs to raise the wrist without contacting the user's body, and the body temperature can be measured. The comfort is high and the measurement scene is also Wider.

Alternatively, in another specific implementation, the temperature sensor 11 may also be a contact sensor, and the contact temperature sensor requires the sensor to be in contact with the object to be measured when measuring temperature. That is, in this way, when the user raises the wrist to measure the body temperature, the smart watch can be brought into contact with the forehead, so that the temperature sensor 11 is in contact with the user’s forehead, so that the temperature sensor 11 can measure the temperature of the forehead, and the display 15 of the smart watch is Can display the user's current body temperature. This application has no particular limitation on the type of the contact temperature sensor, which may include, but is not limited to: at least one of a pressure thermometer, a resistance thermometer, a bimetal thermometer, and a glass liquid thermometer.

The display 15 can display various contents. For example, in the a interface shown in FIG. 5, the display 15 may display time information; for another example, on the c interface shown in FIG. 5, the display 15 may display prompt information. In a specific implementation, the user can control the operation of the smart watch through the touch screen 15. For example, the user can switch the content displayed on the display 15 by sliding, tapping, long-pressing and other operations with a finger, or control the smart watch to realize functions such as heart rate measurement and body temperature measurement.

The human-computer interaction interface shown in FIG. 5 is now used to describe the body temperature measurement process shown in FIG. 4. On the interface a shown in FIG. 5, the current time can be displayed on the display 15 of the smart watch, which is 09:34 in the morning of August 26 (24-hour clock), and today is Monday. The user can slide up and down on the display 15 to switch the content displayed on the display 15. Exemplarily, after the user's finger slides down on the display 15 at least once, the display 15 may present an interface b as shown in FIG. 5. On the b interface, a virtual button for temperature measurement is displayed, and the user can click the virtual button to measure the body temperature. When the user clicks the virtual button, the display 15 of the smart watch displays a prompt message as shown in the c interface, "Start measurement, please aim at your forehead". In this way, the user can raise the wrist so that the smart watch is aimed at the forehead. At this time, the temperature sensor 11 can measure the temperature of the user's forehead. And after the measurement, the current body temperature of the user is displayed on the display 15 of the smart watch.

It can be understood that FIG. 5 is only exemplary, and there may be many changes in the actual scene. For example, in a possible scenario, the b interface as shown in 5 may not be displayed. When the user switches the display 15 to the temperature measurement interface, the c interface can be directly displayed, and the user is prompted to raise his hand to perform the temperature measurement. measuring. For another example, in another possible scenario, on the c interface shown in FIG. 5, the user can also be prompted to point the smart watch at the ear. At this time, the temperature sensor 11 can measure the tympanic membrane temperature in the ear.

In another possible embodiment of the present application, after the smart watch measures the user’s body temperature and displays it on the display 15 (interface d as shown in Fig. 5), the user can also click on the display 15 to Return to the b interface as shown in FIG. 5, or the user can also switch the content displayed on the display screen 15 to other functional content by sliding up and down. For example, the user can swipe up on the display screen 15 so that the display screen 15 displays content as shown in the a interface. For another example, the user can slide down on the display screen 15 so that the display screen 15 displays related content of the heart rate detection.

In the embodiment of the present application, the number of temperature sensors provided in the smart watch may be at least one. In a specific implementation scenario, in addition to the temperature sensor 11, other temperature sensors may also be provided in the smart watch.

Exemplarily, FIG. 6 shows a schematic structural diagram of another electronic device. As shown in FIG. 6, in addition to the temperature sensor 11 and the display 15, a temperature sensor 12 is also provided on the front of the smart watch.

In the embodiment of the present application, the temperature sensor 12 may be the same as the temperature sensor 11. For example, both the temperature sensor 12 and the temperature sensor 11 may be infrared thermopile sensors. At this time, both the temperature sensor 12 and the temperature sensor 11 can be arranged on the front of the smart watch, so that when the user raises the wrist so that the smart watch is aimed at the user's forehead, both the temperature sensor 12 and the temperature sensor 11 can measure the forehead temperature. Therefore, the user's body temperature displayed on the display 15 of the smart watch can be the average value of the forehead temperatures measured by the two temperature sensors, or it can also display the comparison of the two measured temperatures (the forehead temperature measured by the temperature sensor). Temperature) The average temperature after correction.

In another embodiment of the present application, the temperature sensor 12 and the temperature sensor 11 may be different. For example, the temperature sensor 11 may be an infrared thermopile sensor, which is used to measure the forehead temperature when the smart watch is pointed at the user's forehead; and the temperature sensor 12 may be used to measure the ambient temperature. At this time, the body temperature data displayed on the display 15 of the smart watch may be obtained after processing the forehead temperature measured by the temperature sensor 11 and the ambient temperature measured by the temperature sensor 12. The processing method will be detailed later.

When the temperature sensor 12 is an ambient temperature sensor, the ambient temperature sensor may be arranged on the front of the smart watch, as shown in FIG. 6; or, referring to FIG. 7, the temperature sensor 12 may be arranged on the side wall of the smart watch. For example, in a specific scenario, if the temperature sensor 11 is a contact sensor, then the user can measure the forehead temperature by raising the wrist so that the front of the smart watch is in contact with the user's forehead. At this time, the ambient temperature sensor 12 can be installed on the side wall of the smart watch as shown in FIG. 7 to avoid the temperature sensor 12 coming into contact with the user’s skin when the smart watch is in contact with the user’s forehead. The measurement accuracy of the temperature sensor 12 is improved. For another example, in another possible scenario, if the temperature sensor 11 is an infrared thermopile sensor, the forehead temperature can be measured without contacting the user's forehead. At this time, the ambient temperature sensor 12 can be set on the front or side wall of the smart watch. .

It should be noted that FIG. 7 only exemplarily shows the location of the temperature sensors (11 and 12) in the smart watch. In an actual scenario, when the temperature sensor 11 is a non-contact sensor, the outer surface of the temperature sensor 11 may be on the same surface as the outer surface of the front housing of the smart watch, or may be protruding from the front housing of the watch, or may be comparable. Compared with the case of the watch, the front case is recessed. When the temperature sensor 11 is a contact sensor, the outer surface of the temperature sensor 11 may be on the same surface as the outer surface of the front housing of the smart watch, or may be protruding from the front housing of the watch. When the temperature sensor 12 is an ambient temperature sensor, its outer surface can be on the same surface as the outer surface of the front case of the smart watch, or it can be protruding compared to the front case of the watch, or can be concaved compared to the front case of the watch. This is not limited in the embodiments of this application. In addition, the present application does not specifically limit the temperature measurement principle and model of the ambient temperature sensor 12, and only a sensor capable of measuring the ambient temperature is required.

In the embodiment shown in FIG. 6 or FIG. 7, the user's body temperature displayed on the display screen 15 can be obtained by combining the forehead temperature measured by the temperature sensor 11 and the ambient temperature measured by the temperature sensor 12, specifically The processing method will be detailed later. This implementation manner takes the ambient temperature into consideration, so that the user's body temperature displayed on the display screen 15 is closer to the real core body temperature of the human body, and the accuracy of the measurement result is higher.

The structure of the smart watch shown in Figures 5 to 7 is schematic. In the embodiments of the present application, there is no particular limitation on the actual location, size, and data of each temperature sensor on the front and side of the smart watch. In the actual scene, It can be adjusted and designed according to actual product needs.

For example, as shown in FIG. 5, the temperature sensor 11 may be arranged above the display screen 15, or may be arranged below the display screen 15 as shown in FIG. In addition, the temperature sensor 11 can also be arranged at any position on the front of the smart watch. For another example, in the smart watch shown in FIG. 6, the temperature sensor 11 and the temperature sensor 12 may be respectively arranged above or below the display screen 15, or the temperature sensor 11 and the temperature sensor 12 may also be arranged adjacently. Not exhaustively. In addition, in some special implementation scenarios, the temperature sensor 11 and/or the temperature sensor 12 may also be arranged on the outer surface of the smart watch band, and the two may be arranged adjacently or separately. The temperature sensor 11 and the temperature sensor 12 may be respectively connected to the processor of the smart watch, so that the processor obtains the user's body temperature according to the measured temperature data, and displays it on the display screen 15. Wherein, the connection mode may be a wired connection, and the connection line may be buried inside the watchband or exposed on the surface of the watchband (at least one of the inner surface, the outer surface, and the side wall) through other designs.

In the embodiment of the present application, the body temperature measurement result may be displayed on the display screen 15 of the smart watch, as shown in FIG. 5; in addition, the body temperature measurement result may also be displayed on other electronic devices connected to the smart watch. The connections involved here can include, but are not limited to, wired connections or wireless connections. For example, a smart watch can be connected to a computer through a data cable, and the user's body temperature measurement results can be displayed on the computer. For another example, a smart watch can also be connected to a mobile phone via Bluetooth, and display the user's body temperature measurement result on the display interface of the mobile phone.

Exemplarily, FIG. 8 is a schematic diagram showing the body temperature measurement result of a smart watch on a mobile phone. At this time, the smart watch and the mobile phone 200 can be connected via Bluetooth, WiFi or other means. The smart watch can transmit the measured user's data to the mobile phone 200. In this way, the user opens a designated application (APP), for example, a sports health APP , You can check your body temperature on the display interface of the APP.

As shown in FIG. 8, compared to a smart watch, the mobile phone 200 can display more body temperature data when displaying the user's body temperature data. For example, on the display interface as shown in FIG. 8, the average body temperature, the highest body temperature and the lowest body temperature of the user in the last week, and the most recent (measured body temperature) can be displayed. for example. If the user uses the aforementioned method within the last week, raise his hand to measure his body temperature. The user raised his hand and measured 8 times in total. Based on the measurement data, the user's body is as follows: 38℃, 37.3℃, 36.8℃, 36.5℃, 36.1℃, 36℃, 36.3℃, 36.8℃, at this time, as shown in Figure 8. As shown, the body temperature card can provide users with the following information: the user’s average body temperature in the last week is 36.7℃, the user’s highest body temperature in the last week is 38℃, the user’s lowest body temperature in the last week is 36℃, and the user’s The measured body temperature was 36.8°C.

The description of the interface and touch operation shown in FIG. 8 will be detailed later.

This application also provides another body temperature measurement method, as shown in FIG. 9, this method does not require the user to raise the wrist, and the smart watch can automatically measure the user's body temperature when the user wears the smart watch daily. In this scenario, there is no need for the user to make a specified action or operation, and the user can perform daily routines normally. For the user, this method of body temperature measurement is more comfortable and convenient.

In specific implementation, the solution can be implemented by a temperature sensor provided on the back of the smart watch (the outer surface of the side that is in contact with the user's wrist skin).

In a possible embodiment, referring to FIG. 10, a temperature sensor 13 is provided on the back of the smart watch (the outer surface of the side in contact with the user's wrist skin). In this way, when the user normally wears the smart watch, the temperature sensor 13 can be in contact with the user's skin, and can be specifically used to measure the user's skin surface temperature (that is, the temperature of the wrist shown in FIG. 1), which can be denoted as Ts .

Exemplarily, FIG. 11 shows a schematic diagram of a body temperature measurement principle provided by an embodiment of the present application. As shown in Figure 11, when a user wears a smart watch, the temperature sensor 13 is in contact with the user’s skin, and the skin surface temperature Ts at the user’s wrist can be measured. Thus, the user’s body temperature T displayed in the smart watch or mobile phone is It can be obtained after correcting Ts.

As shown in Fig. 11, the temperature sensor 13 can realize automatic measurement. When the user triggers the automatic body temperature measurement function of the smart watch (detailed later), the smart watch can automatically measure the user's body temperature. For example, the temperature sensor 13 may periodically measure temperature data, for example, once every 1 hour. For another example, the temperature sensor 13 can measure temperature data at a preset time. For example, the temperature sensor 13 can automatically measure temperature data at 6:00, 12:00, 16:00, 19:00, and 21:00 every day. Therefore, by correcting each measured temperature data, the user's body temperature data at these moments can be displayed in the smart watch. For example, if the temperature sensor 13 obtains 5 pieces of measurement data T s1 to Ts5, then after correction processing, 5 pieces of temperature data T1 to T5 can be obtained. Therefore, the temperature T after correction for Ts can be displayed on the display screen 15 of the smart watch or the mobile phone 200 connected to it.

In addition, the number of temperature sensors 13 may be one or more, and the location of the third sensor 13 may be any position on the back of the smart watch or the back of the strap.

In the embodiment shown in FIG. 10, the smart watch can realize continuous measurement of the user's body temperature, which can meet the requirements of continuous measurement of body temperature in scenarios such as women's menstrual cycle management, biological rhythm regulation, and chronic disease management. Moreover, this measurement process is convenient and comfortable for the user. In addition, the embodiment of the present application also improves the measurement accuracy of the body temperature measurement result output by the smart watch by correcting the measured body temperature.

In addition, FIG. 11 further shows the relationship between the human skin surface temperature (denoted as Ts) and the deep skin temperature (denoted as Td). For the human body, the skin surface temperature Ts and the deep skin temperature Td are generally different. Under normal circumstances, the deep skin temperature Td is generally higher than the skin surface temperature Ts. The temperature difference between the skin surface temperature Ts and the deep skin temperature Td is related to the heat flux HF. Among them, heat flux can also be called heat flow or heat flux density, which refers to the heat energy passing through a certain area per unit time. It is a directional vector. The unit in the International System of Units is Joules per second (J /s), which is watts (W). As shown in FIG. 12, the skin surface temperature Ts, the skin deep layer temperature Td, and the heat flux HF may satisfy the following relationship: Td=Ts+HF×R, where R represents the skin thermal resistance. Thermal resistance refers to the ratio between the temperature difference between the two ends of the object and the power of the heat source when heat is transferred to the object, in units of Kelvin per watt (K/W) or degrees Celsius per watt (°C/W). For example, the thermal resistance of the human skin can be. Therefore, when the skin surface temperature Ts and heat flux HF are measured, the skin deep layer temperature Td can be obtained; conversely, if the skin deep layer temperature Td and heat flux HF are measured, it can be obtained Skin surface temperature Ts.

Therefore, in the embodiments of the present application, it is also possible to measure the deep skin temperature Td and correct the deep skin temperature Td to display the temperature after the Td correction.

Figures 12 and 13 show this design. A temperature sensor 14 is provided on the back of the smart watch (the outer surface of the side that is in contact with the user's wrist skin). In this way, when the user normally wears the smart watch, the temperature sensor 14 can be in contact with the user's skin, and can be specifically used to measure the user's deep skin temperature Td or heat flux HF.

In the embodiment shown in FIG. 12, the temperature sensor 14 can be used to measure the deep skin temperature Td. In a possible embodiment, the temperature sensor 14 may be provided with two temperature measurement modules and processors. One measurement module may be used to measure the temperature Ts of the two skin surfaces, and the other may be used to measure the heat flux HF, and the processing The device can be used to obtain the deep skin temperature Td at the user's wrist according to Ts and HF, and output Td. When the user wears the smart watch, the temperature sensor 14 is in contact with the user's skin, and the deep skin temperature Td at the user's wrist can be measured. In this way, the smart watch can display the temperature T after the Td is corrected.

At this time, the temperature sensor 14 may be a heat flux sensor. The heat flux sensor, also known as the heat flow sensor, can be used to measure the deep temperature of an object. The measurement principle is that the deep temperature of the object can be obtained by measuring the heat flux between the depth of the object and the surface, and combining it with the surface temperature of the object. Therefore, only one heat flux sensor can be provided on the back of the smart watch, that is, the deep skin temperature Td of the user can be measured.

In the embodiment shown in FIG. 13, the temperature sensor 14 may also be a heat flux sensor, but the heat flux sensor may be used to measure the heat flux HF, or to measure the deep skin temperature Td.

The temperature sensor 14 can be used to measure the heat flux HF. In this case, it is also necessary to combine the skin surface temperature Ts measured by the temperature sensor 13 to obtain the deep skin temperature Td. Therefore, in this embodiment, the temperature sensor 13 and the temperature sensor 14 are provided on the back of the smart watch. After obtaining Ts and HF, the processor of the smart watch can determine Td, and then display the body temperature T obtained after Td is corrected.

Alternatively, the temperature sensor 14 can be used to measure the deep skin temperature Td. At this time, the smart watch can determine the user's body temperature T according to the skin surface temperature Ts and the skin deep temperature Td. For example, a smart watch can use the skin surface temperature Ts and a preset HF to make a preliminary correction to the skin deep layer temperature Td to obtain Td'. Thus, in the smart watch, the body temperature T after the Td' is corrected is displayed. Among them, when using Ts and HF to make preliminary corrections to Td, the deep skin temperature Td" corresponding to Ts and HF can be obtained in the manner shown in Figure 11, thereby obtaining the average value (or weighted average) of Td" and Td, Get the corrected Td'.

Compared with the skin surface temperature Ts, the deep skin temperature Td has a smaller change and is relatively more stable. Therefore, the corresponding relationship between the deep skin temperature Td and the user's body temperature T is also more stable, as shown in Figure 12 and Figure 13. In the illustrated embodiment, the use of Td to obtain the body temperature T can improve the accuracy of the correction result to a certain extent, and increase the closeness between the body temperature T and the user's actual body temperature, which is conducive to obtaining a more accurate body temperature measurement result. , The stability is also higher.

In addition, the embodiments shown in FIG. 12 and FIG. 13 can also implement continuous measurement, such as periodic measurement or timing measurement, to meet the requirements of continuous body temperature measurement in scenarios such as women's menstrual cycle management, biological rhythm regulation, and chronic disease management. Likewise, this measurement process is convenient and comfortable for the user.

It should be noted that in the embodiments of the present application, a temperature sensor can be separately provided on the front of the smart watch. For example, in the embodiments shown in Figures 4 to 8, the user can actively raise his hand to measure his body temperature; or, A temperature sensor can be separately provided on the back of the smart watch. For example, in the embodiments shown in FIGS. 9-13, after the user turns on the automatic temperature measurement function, the smart device 100 can automatically measure the user's body temperature.

In actual implementation scenarios, the foregoing two measurement methods can be combined.

Exemplarily, FIG. 14 shows a schematic structural diagram of another smart watch. As shown in Figure 14, the smart watch is equipped with 4 temperature sensors: the temperature sensor 11 is installed on the front of the smart watch and used to measure the temperature of the user's forehead (or ear, etc.); it is installed on the side of the smart watch and used to measure the environment Temperature sensor 12; temperature sensor 13 arranged on the back of the smart watch and used to measure the surface temperature of the user's skin; temperature sensor 14 arranged on the back of the smart watch and used to measure the deep layer temperature of the user's skin. And, a display 15 is also provided on the front of the smart watch.

It can be understood that FIG. 14 also only exemplarily shows the positions of the temperature sensors. In actual scenarios, the temperature sensor 13 can be used to measure the temperature of the user’s skin surface, and the temperature sensor 14 can be used to measure the deep layer temperature or heat flux of the user’s skin. Therefore, the outer surfaces of the two temperature sensors can be used to measure the temperature of the skin on the back of the smartwatch. The external surface is on the same surface, or it can be arranged protrudingly compared to the back shell of the watch.

In the smart watch shown in FIG. 14, each temperature sensor can measure temperature data in the manner described in the previous embodiment, and the smart watch can also display the user's body temperature measurement result (body temperature T ). Do not repeat it.

In addition, in this embodiment, the user's body temperature T displayed in the electronic device 100 may also be calculated based on the measurement data of each temperature sensor.

Exemplarily, reference may be made to FIG. 15, which shows a schematic diagram of another body temperature measurement method of the embodiment shown in FIG. 14. On the one hand, the temperature sensor 11 can measure the user's forehead temperature Tf when the user raises the wrist; while the temperature sensor 12 can measure the ambient temperature Te; then, the ambient temperature Te can be used to correct the forehead temperature Tf to obtain the user The forehead body temperature Tc. On the other hand, the temperature sensor 13 can measure the skin surface temperature Ts of the user, and the temperature sensor 14 can be used to test the heat flux HF between the skin surface and the deep skin layers; then the user's deep skin temperature Td can be obtained from this. . In this way, the forehead body temperature Tc can be used to correct the deep skin temperature Td, so as to obtain the user's body temperature measurement result and display it. The specific correction method will be described in detail later.

In the smart watch shown in FIG. 14, the temperature measurement results of multiple temperature sensors can be combined to finally determine the user's body temperature T, which can improve the accuracy of the determined body temperature T to a certain extent.

In the embodiments of the present application, in the embodiments shown in FIGS. 10-15, the body temperature measurement results obtained by the smart watch can be displayed on the display 15 of the smart watch, or can be displayed on the mobile phone 200 connected to the smart watch. on. Specifically, it may be displayed on the display interface of the sports health APP of the mobile phone 200.

Exemplarily, FIG. 16 shows a schematic diagram of an interpersonal interaction scene.

When the user opens the sports health APP, the mobile phone can present an interface as shown in FIG. 16. The a interface includes: multiple tab page controls (for example, home page control 201), a tab bar 202, a body temperature card 203, a heart rate card 204, and a card management control 205. Among them, the homepage control 201 is in a selected state to remind the user that the user is currently on the APP homepage interface. In addition, if the user clicks on other controls, he can enter the corresponding display interface of the tab control. For example, if the user clicks on the device control, the corresponding content of the device tab is displayed on the display interface of the mobile phone 200. The embodiment of the present application does not limit the display mode and content of the corresponding content of each tab page.

On the interface a in Fig. 16, the tab bar 202 can be used to display device information. For example, the content that can be displayed includes but is not limited to: operator information (China Mobile), operator signal strength, current time information (09:34), power information. In addition, the tab bar 202 may also display user information, such as at least one of a user profile picture and a user name. Among them, the user avatar and user name displayed here may be the default settings of the sports health APP, or they may be modified or set by the user. In addition, a connection state control 2021 is also provided in the tab bar 202, and the connection state control 2021 is used to indicate the connection state between the mobile phone 200 and the smart watch. For example, when the mobile phone 200 is connected to the smart watch with Bluetooth, the connection status control 2021 displays "connected"; when the mobile phone 200 and the smart watch are disconnected from the Bluetooth connection, the connection status control 2021 may display "not connected". It can be understood that the tab bar 202 can display more or less content. For example, the WiFi connection status may also be displayed; for another example, the current time information may not be displayed in the tab bar 202.

The body temperature card 203 is used to display the body temperature of the user. As shown in the interface a in Figure 16, multiple body temperature data can be displayed on the body temperature card 203: the average body temperature, the most recent (measured body temperature), the highest body temperature, and the lowest body temperature. Among them, the average body temperature, the highest low temperature, and the lowest body temperature can be data statistics results in the same time interval. For example, on the interface a in FIG. 16, the body temperature card 203 may display the user's body temperature statistics data in the most recent day. There are other ways, which will be described in detail later.

The heart rate card 204 is used to display the user's heart rate data. As shown in the interface a in Figure 16, the heart rate card can display multiple heart rate data: resting heart rate, the most recent (measured heart rate), the highest heart rate and the lowest heart rate.

The card management control 205 is used to manage the content cards displayed on the homepage. Through the card management control 205, the user can adjust which content cards are displayed on the homepage interface. For example, through the card management control 205, the user can add other content cards on the homepage interface, such as sleep cards (used to display the user's sleep status), exercise cards (used to display the user's exercise steps, running time, running distance and other information ); And, the user can also delete the heart rate card 204 from the homepage interface, so that the user's heart rate is no longer displayed on the homepage interface. In addition, through the card management control 205, the user can also adjust the display order of the content cards. For example, the heart rate card 204 can be displayed above the body temperature card 203.

The user can click the body temperature card 203 on the a interface, so that the mobile phone 200 displays the b interface as shown in FIG. 16, and the user can view the detailed information of the user's body temperature on the b interface.

On the b interface shown in FIG. 16, the time interval 206, the body temperature curve 207, and the statistical information 208 can be displayed.

Exemplarily, the time interval 206 may show one or more time intervals. For example, the body temperature in a certain time interval, such as the last week, can be displayed by default. For another example, the b interface as shown in FIG. 16 can display multiple different time intervals. For example, the time interval represented by "day" is the most recent day. Specifically, it may be the most recent 24 hours or a day of a natural day. It is still a time interval from 0:00 to 23:59 every day. In addition, the time interval in FIG. 16 is illustrative and should not constitute a limitation in the actual scenario. For example, the time interval can also be set to the last three days, which are all within the scope of the present application.

The ordinate of the body temperature curve 207 is body temperature, and the abscissa is time, which is used to indicate the change of the user's body temperature in the current time interval. The statistical information 208 displays the statistical data of the user's body temperature in the current time interval, and the specific displayed content may include, but is not limited to: the average body temperature, the highest body temperature, the lowest body temperature, and the most recent body temperature. For example, on the b interface shown in Figure 16, if the currently selected time interval is "day", the body temperature curve 207 shows the user's body temperature change curve in the most recent day, and the body temperature information display shows the user's body temperature during this day. The average body temperature, the highest body temperature, the lowest body temperature, the most recent body temperature, and information about whether an abnormality has occurred.

In the embodiment of the present application, the statistical information 208 further displays the abnormality prompt information 2081. When the user's body temperature is abnormal, it displays "Is there an abnormality: Yes"; otherwise, if there is no abnormality, it displays "Is there an abnormality: None" . In specific implementation, the user's body temperature in the current time interval can be compared with a preset body temperature threshold, and it can be determined whether the user's body temperature is abnormal. For example, a high temperature threshold may be preset, such as 37.3°C, so that, as shown on the b interface, the user's highest body temperature in the most recent day is 38°C, which is greater than the high temperature threshold, and it is determined that the user's body temperature is abnormal. In an actual scenario, the body temperature threshold can be set to at least one of a high temperature threshold and a low temperature threshold. It can be understood that if the user's body temperature is less than (or equal to) the low temperature threshold, it can be determined that the user's body temperature is abnormal. It should be noted that the abnormality prompt information 2081 can be implemented after the body temperature abnormality reminder function is turned on. If the function is not turned on, the abnormality prompt information 2081 may not be displayed, or, for example, the abnormality prompt information 2081 may be displayed as "abnormality prompt The function is not turned on, you can turn it on on the device settings page". The method for turning on the abnormal temperature reminder function will be described in detail later (Figure 19).

In one embodiment of the present application, the user can adjust the time interval 206 so that the body temperature curve 207 and the statistical information 208 display body temperature data in different time intervals. The user can click (or slide, voice command, gesture action, etc.) to adjust the time interval of the touch operation. For example, the user can click "week", and the mobile phone 200 can display the c interface shown in FIG. 16. On the c interface, the user's body temperature change curve and statistical data in the last week are displayed, so I won't repeat it. Similarly, the user can also make further adjustments on the c interface to view the user's detailed body temperature data in the most recent month or the most recent year.

After viewing the detailed body temperature data, the user can also return to the homepage interface of the sports health APP. For example, you can click the return control 209 on the c interface to return to the home page interface. For another example, it is also possible to return to the homepage interface through voice instructions, designated action gestures (such as drawing a "C" shape), hiding the return button, and so on.

As shown in FIG. 16, after the user clicks the return control 209, the user can enter the d interface shown in FIG. 16. At this time, the time interval corresponding to the body temperature data displayed on the body temperature card 203 displayed on the homepage interface is consistent with the time interval on the body temperature details interface. Therefore, the body temperature data displayed on the body temperature card 203 is the same as the statistical information 208 displayed on the body temperature details interface. For example, in FIG. 16, the display data of the temperature card 203 on the a interface and the statistical information 208 on the b interface are consistent. For another example, in Figure 16, the statistical information on the c interface is also consistent with the data displayed on the body temperature card on the d interface.

Therefore, in the implementation scenario shown in FIG. 16, the time interval of the body temperature card 203 displayed on the home page interface can be adjusted by adjusting the time interval 206 on the body temperature details interface.

In addition, in this embodiment of the present application, the user can also directly adjust the time interval of the body temperature card on the homepage interface. Refer to the schematic diagram of another human-computer interaction scenario shown in FIG. 17.

The a interface shown in FIG. 17 is the homepage interface of the sports health APP, and the body temperature card 203 is displayed on the homepage interface. In the embodiment of the present application, a time control 2031 is displayed in the body temperature card 203, and the time control 2031 can be used to display the time interval corresponding to the body temperature data currently displayed by the body temperature card 203. For example, the body temperature card 203 on the a interface displays the body temperature statistics data of the most recent week.

The user can adjust the time interval by performing a touch operation on the time control 2031. As shown in Figure 17, the user can click on the time control 2031 on the a interface. At this time, the selection bar 2032 of the time interval can be superimposed on the current interface, the cancel control 2033, and the confirm control 2034, as shown in the b interface of Figure 17 . As shown in FIG. 17, a plurality of different time intervals are displayed on the selection bar 2032, and the user can make a sliding selection on the selection bar to determine the time interval of the user's preference. For example, the user slides in the selection column 2032 to adjust the currently selected time interval "last week" to "last day". Therefore, on the c interface, if the user clicks the cancel control 2033, the mobile phone 200 then displays the a interface, which still displays the user's body temperature statistical data in the last week. Or, if the user further clicks the confirm control 2034, as shown in FIG. 17, the d interface is displayed in the mobile phone 200, and the temperature card in the d interface displays the user's body temperature statistics data in the most recent day. In this way, the user can directly adjust the time interval of the body temperature card 203 on the homepage interface.

In the embodiments of the present application, the embodiment shown in FIG. 17 and the embodiment shown in FIG. 16 can be implemented independently. Alternatively, they can be combined.

For example, in one embodiment, the time control 2031 displayed in the body temperature card 203 is only used to prompt the user. At this time, the user cannot directly adjust the temperature of the body temperature card on the homepage interface through the method shown in FIG. Time interval. Or, the time control 2031 may not be displayed in the temperature card 203. The user can adjust the time interval of the data displayed by the body temperature card 203 in the manner shown in FIG. 16.

For another example, in another embodiment, the time interval corresponding to the body temperature card may not be synchronized with the time interval on the body temperature details interface. At this time, the user can adjust the time interval corresponding to the body temperature card on the homepage interface as shown in Figure 17; and, the user can switch the time interval 206 arbitrarily on the body temperature details interface, as shown in the b interface in Figure 16. But this switch will not affect the time interval of the temperature card. For example, the time interval of the homepage card may be the most recent week, and the time interval viewed by the user on the body temperature details interface may be "year" (that is, the most recent year).

For another example, in another embodiment, the methods shown in FIG. 16 and FIG. 17 can be combined. At this time, the user can click the time control 2031 on the homepage interface to adjust the time interval, and the user can also adjust the time interval on the body temperature details interface. The time interval 206 is adjusted, and these adjustments will be synchronized on the body temperature card and the body temperature details page.

In another embodiment, the time interval corresponding to the body temperature card 203 may also be a default design and cannot be adjusted by the user. For example, the body temperature card 203 can display body temperature data of the most recent day by default. Taking the scene shown in FIG. 16 as an example, at this time, if the user clicks the return control 209 on the c interface, it will return to the a interface shown in FIG. 16.

In addition, in the embodiment of the present application, the electronic device 100 may not provide the user with the authority or function to adjust the time interval. At this time, the time interval displayed by the body temperature card can be determined by the electronic device according to the system preset or the user's usage data.

In one embodiment, when the user opens the sports health APP, for example, on the interface a in FIG. 16, the time interval corresponding to the body temperature card may be a preset time interval. For example, when the sports health app is started, the body temperature card line displays the temperature data of the most recent day by default.

In another embodiment, when the user opens the sports health APP, the time interval corresponding to the body temperature card may be the time interval corresponding to the last time the user closed the sports health APP. For example, if the user opened the Sports Health APP for the first time to view his own body temperature detailed information, he finally checked his own body temperature data for the most recent week; then, when the user opened the Sports Health APP for the second time, the most recent data could be displayed on the a interface. Body temperature data for one week.

In another embodiment, when the user opens the sports health APP, on the interface a in FIG. 16, the time interval corresponding to the body temperature card may be the time interval that the user views the most times. For example, in the last month, a user used the Sports Health APP to check his body temperature data, and he checked it 10 times (without considering switching). Among them, he checked his daily body temperature change 5 times, and his weekly body temperature change 4 times. The monthly body temperature change is checked once, then when the user opens the sports health app again, the user's body temperature data in the most recent day will be displayed on the a interface.

In addition, the heart rate card 204 can also refer to any of the aforementioned designs of the body temperature card 203, which will not be repeated.

In the embodiments of the present application, the body temperature display modes shown in FIGS. 16 and 17 can be applied to any of the foregoing embodiments in FIGS. 3 to 15.

In the body temperature measurement method involved in any of the embodiments in FIGS. 9-15, the smart watch can automatically measure the user's body temperature. In a specific implementation scenario, this automatic body temperature measurement function can be turned on by default, that is, without the user's additional operation, the smart watch can automatically measure the user's body temperature according to a preset period or a predetermined time.

In another embodiment, the user may decide whether to enable the function of automatically measuring body temperature. At this time, you can refer to another human-computer interaction scenario shown in FIG. 18.

After the user opens the sports and health APP of the mobile phone 200, he can enter the homepage interface. At this time, the user can click on the device control 210, so that the mobile phone displays an interface as shown in Figure 18, which is the interface of the device control 210 in the selected state. Tab interface.

On the interface a of FIG. 18, in addition to multiple tab page controls, a device card 211 and a tab bar 212 are also displayed. There may be one or more device cards 211. Figure 18 shows the device cards of three smart wearable devices. Specifically, the device card 211 may include: a device name 2111, a device icon 2112, a Bluetooth connection status 2113, and a device power 2114. Among them, the device name 2111 and the device icon 2112 can be default settings, or can be customized and edited by the user. The Bluetooth connection status 2113 is used to characterize the Bluetooth connection status between the smart watch and the mobile phone 200. For example, the smart watch "Honor Watch Magic" is currently connected to the mobile phone; while the smart watch "Huawei Watch GT" is disconnected from the mobile phone and is not connected. The device power level 2114 refers to the power level of the smart watch, not the power level of the mobile phone 200, and the power level of the mobile phone 200 is displayed in the tab bar 211. For example, the battery of the "Honor Band 3-4fd" smart bracelet is 80%, and the battery of "Honor Watch Magic" is 50%. When the smart wearable device is not connected to the mobile phone, the battery power of the device may not be displayed, as shown in the device card of "Huawei Watch GT".

The user can click on the device card of any smart wearable device to set the smart wearable device. As shown in FIG. 18, the user clicks on the smart card 211 of "Honor Watch Magic" to enter the device setting interface of the smart watch, that is, the interface b in FIG. 18. On the interface b in Figure 18, the user can turn on or turn off the smart watch function. For example, the user can turn on the sedentary reminder function of the smart watch. For another example, the user can turn off the function of automatically measuring heart rate. The user can turn on or off the automatic temperature measurement function. On the b interface, if the automatic body temperature measurement function is currently in the "off" state, the user can click the body temperature setting control 213, so that the mobile phone can jump to the body temperature setting interface, that is, the c interface. On the c interface, explain the automatic temperature measurement function provided by the smart watch. Exemplarily, the c interface specifically shows the wearing mode of the smart watch and the text description: "24 hours smart monitoring of your body temperature. For accurate measurement, please wear your watch tightly." Exemplary, the c interface also shows the right The reminder information of the user will not be described in extra detail. Through the relevant instructions on the c interface, the user can understand the automatic temperature measurement function and determine whether to turn on the function according to their needs. When the user wants to turn on the automatic body temperature measurement function, he only needs to click the turn-on control 214 on the c interface. Then, on the setting interface (interface d) of the smart watch, the automatic body temperature measurement function is in the "on" state. In this way, the smart watch can automatically measure the user's body temperature.

It is understandable that if the automatic body temperature measurement function is in the "on" state on the smart watch setting interface, the user can also click the body temperature setting control 213 to enter the body temperature setting interface, and then click to close the control (not shown in Figure 18) Out) to turn off the function.

In addition, the user can also click on the abnormal temperature reminder control 215 on the device setting interface, as shown in the a interface in Figure 19, to enter the b interface as shown in Figure 19, and turn it on or off on the b interface Abnormal body temperature reminder function. As shown in FIG. 19, the interface b displays: a control 216 for controlling the abnormal temperature reminder switch, a control 217 for controlling the default reminder switch, and a control 218 for controlling the manual setting reminder threshold function switch. It can be understood that when the control 216 is in the open state, the control 217 and the control 218 can be turned on or off; moreover, the control 217 and the control 218 can only be turned on, that is, the abnormal body temperature can only be performed according to the threshold set by default. Remind (when the control 217 is turned on), or remind according to the reminder threshold set by the user (when the control 218 is turned on).

On the b interface shown in FIG. 19, the abnormal temperature reminder function is currently in the off state, and the user can click the control 216. At this time, you can refer to the c interface, and the abnormal temperature reminder function is enabled. At this time, the user can click the control 217 or click the control 218. If the user clicks on the control 218, the user can perform a touch operation on the control 2181 to set the user's favorite temperature abnormality reminder upper limit; and/or the user can also perform a touch operation on the control 2182 to set the user's favorite temperature abnormality Remind the lower limit. For example, if the user sets the upper limit of the abnormal temperature reminder to 37.3°C and the lower limit of the abnormal temperature reminder to 36.2°C, the setting interface can be converted from the c interface to the d interface. After the user setting is completed, the smart watch or mobile phone can perform the abnormal temperature reminder according to the preset upper threshold and/or lower threshold of the abnormal temperature reminder, as shown in the b interface in Figure 16, and will not be repeated.

The body temperature measurement method provided in the embodiments of the present application will now be described in detail.

In a possible implementation scenario, when an infrared thermopile sensor 11 is provided on the front of the smart watch, for example, as shown in Figs. 5-7 and 14, Fig. 20 shows a body temperature measurement method in this case Schematic diagram.

When the user raises the wrist and makes the infrared thermopile sensor 11 on the front of the smart watch aim at the user's forehead, the infrared thermopile sensor 11 can measure the temperature Tf at the user's forehead and transmit the measured temperature Tf to the processor 110, thereby After the processor 110 receives the measured temperature Tf, it can directly output Tf.

It should be noted that the processor 110 can output Tf to the display 15 so that Tf can be displayed on the display of the smart watch. Alternatively, when the smart watch is connected to the mobile phone 200 via Bluetooth, Tf can also be output to the mobile phone, so that Tf can be displayed in the sports health APP of the mobile phone. This will not be repeated in the follow-up.

In another possible implementation scenario, when an infrared thermopile sensor 11 is provided on the front of the smart watch, and an ambient temperature sensor 12 is provided on the front or side, for example, as shown in FIG. 6, FIG. 7, FIG. 14, and FIG. 21 A schematic diagram of a body temperature measurement method in this scenario is shown.

When the user raises the wrist and makes the infrared thermopile sensor 11 on the front of the smart watch aim at the user's forehead, the infrared thermopile sensor 11 can measure the forehead temperature Tf, and the ambient temperature sensor 12 can measure the current ambient temperature Te. After the processor 110 receives the measured temperatures Tf and Te, it uses Te to correct the Tf to obtain the corrected temperature Tc. In this way, it outputs and displays Tc.

In a possible embodiment, the corresponding relationship between the measured temperature Tf, Te and Tc can be preset. For example, a temperature correspondence table can be established in advance. In this way, when the processor 110 receives Tf and Te, it can determine the value of Tc corresponding to the measured temperature by looking up the table, and then output it.

Table 1

环境温度Te(℃)Environment temperature Te(℃)	2525	3030
额头温度Tf(℃)Forehead temperature Tf(℃)	36.636.6	36.636.6
校正后额头处体温Tc(℃)Body temperature Tc at the forehead after correction (℃)	36.836.8	36.736.7

Exemplarily, you can refer to the temperature correspondence table shown in Table 1. For example, in one embodiment, when the temperature (Tf) measured by the temperature sensor 11 is 36.6°C, and the temperature (Te) measured by the temperature sensor 11 is 25°C, you can look up Table 1 to get the corrected body temperature at the forehead (Tc) is 36.8°C, then 36.8°C is displayed on the display 15 of the smart watch.

For another example, the processor 110 may collect sample data of Tf, Te, and Tc, and perform curve fitting on the sample data to obtain a mathematical formula between the three, and use the mathematical formula as a corresponding relationship. In this way, the processor When Tf and Te are received, the value is brought into the mathematical formula to get the corresponding Tc value. The correspondence relationship or correspondence table between the three can be stored in any location that can be called by the processor, for example, stored in the internal memory 121.

In addition, the body temperature measurement method shown in FIG. 21 is also applicable to a possible situation: the front of the smart watch is provided with an infrared thermopile sensor 11, and when the ambient temperature sensor 12 is not provided, the processor 110 can receive Tf, and obtain the ambient temperature through other methods, and further, the processor 110 may also determine and output Tc in the manner shown in FIG. 21.

In an embodiment, the default ambient temperature may be set in the processor 110 in advance. For example, the environmental temperature can be set to 25°C by default; for example, the environmental temperature in summer (June to September) can be set to 30°C, and the environmental temperature in winter (December to February) can be set to 15°C. In this case, the processor 110 may select different ambient temperatures for processing according to the current time.

In another embodiment, the smart watch may also obtain the current temperature recorded on the network through communication, and use it as the ambient temperature. For example, the smart watch can communicate with the mobile phone 200 via Bluetooth. When the Bluetooth is connected, the mobile phone 200 can send the temperature data of the day recorded by its own weather module to the smart watch. At this time, the temperature data sent by the mobile phone 200 can be a temperature data, such as 23°C; or a temperature table indicating the weather conditions at each time, for example, 23°C at 12:00 and 21°C at 14:00. Wait. For another example, a smart watch can access the network through WiFi, or access a cellular network through an LTE (Long Term Evolution) module, so that the temperature data provided by the weather server is used as the ambient temperature to perform the operation shown in Figure 21. deal with. Among them, the LTE module can support LTE networks and their evolved networks, such as 3G networks, 4G networks, and 5G networks.

In a possible implementation scenario, one or more temperature sensors are provided on the back of the smart watch. For example, the back of the smart watch shown in FIG. 10 is provided with a surface temperature sensor 13, another example, the back of the smart watch shown in FIG. 11 is provided with a heat flux sensor 14, another example, the smart watch shown in FIG. 13 or FIG. A surface temperature sensor 13 and a heat flux sensor 14 are provided on the back of the device.

At this time, the processor can receive the temperature measured by the temperature sensor and directly output the received temperature. For example, in the scene shown in FIG. 10, the smart watch can measure the skin surface temperature Ts through the surface temperature sensor 13, and display the skin surface temperature Ts on the display screen 15. For another example, in the scene shown in FIG. 11, the smart watch can measure the deep skin temperature Td through the heat flux sensor 14 and display the deep skin temperature Td on the display 15.

In the scenario shown in Figure 13 or Figure 14, the processor can also calculate the deep skin temperature Td after receiving the skin surface temperature Ts and the heat flux HF measured by the temperature sensor, and output the deep skin temperature Td . Thus, the deep skin temperature Td can be displayed on the display 15 of the smart watch.

In another possible implementation scenario, an infrared thermopile sensor 11 is provided on the front of the smart watch, as shown in Figures 5 to 7, and 14; and the back of the smart watch is also provided with a surface temperature sensor 13, such as 10. As shown in Figure 13-14.

At this time, FIG. 22 shows a schematic diagram of a body temperature measurement method in this scenario.

Specifically, the infrared thermopile sensor 11 works when the user raises the wrist to aim at the forehead, and the surface temperature sensor 13 can periodically or regularly collect the skin surface temperature of the user. Since the skin surface temperature collected by the surface temperature sensor 13 may not be stable and may be quite different from the body temperature of the human body, the temperature of the forehead can be used to correct Ts to obtain a temperature closer to the actual body temperature of the human body. Body temperature measurement result.

As shown in FIG. 22, the processor 110 can receive the measurement data, Tf and Ts, respectively collected by the infrared thermopile sensor 11 and the surface temperature sensor 13, and use the first corresponding relationship to correct Ts, thereby obtaining the user's body temperature after T , Output. The first corresponding relationship between Tf and Ts may be established in the processor 110 and stored in a storage location readable by the processor 110.

In a possible embodiment, the first correspondence may be a weighting function. For example, the weighting function can be expressed as: T=w1*Tf+w2*Ts, where w1 and w2 are preset weights, and the sum of w1 and w2 can be 1, and the application does not limit the specific weight value. Thus, after the processor 110 obtains Tf and Ts, it can bring Tf and Ts into a preset weighting function, obtain the user's body temperature measurement result (body temperature T), and output the body temperature T.

It should be noted that because Tf can be measured when the user is actively measuring, and Ts may be collected by periodic measurement. At this time, Tf and Ts may not be aligned. In this case, whenever a Ts data is collected , Then obtain the Ts value when the user took the initiative to measure the body temperature last time, and then bring the Ts value into the calculation.

For example, the surface temperature sensor 11 in the smart watch automatically measures the temperature data Ts every 1 hour, and the user raises his hand to actively measure the body temperature at 12:00, and the temperature measured by the infrared thermopile sensor 11 is recorded as Tf1; Later, at 14:30, he raised his hand and measured his body temperature again, and the temperature measured by the infrared thermopile sensor 11 was recorded as Tf2. Then, when the processor 110 calculates the body temperature at 14:00, it uses Tf1 to perform weighting processing to obtain the body temperature T and then output; while the smart watch uses Tf2 to perform weighting processing when the body temperature is measured at 15:00 to obtain the body temperature T and then output .

In addition, in order to obtain Ts corresponding to Tf, when the user raises his hand to actively measure the body temperature, the surface temperature sensor 13 may also work, and output the collected Ts to the processor 110. In this way, it is beneficial to obtain a more accurate first correspondence relationship, and it is beneficial to improve the accuracy of the body temperature T thus obtained. Alternatively, if the measurement period of the surface temperature sensor 13 is small enough, for example, once every minute, when the user raises the wrist for active measurement, a more accurate Ts corresponding to Tf can be obtained.

When the smart watch measures body temperature, the data processing method when actively measuring body temperature and the data processing method when automatically measuring body temperature may be the same, for example, both are processed according to the aforementioned weighting function. Then, when the user raises his hand to actively measure body temperature, after the processor receives Tf, if it can receive the Ts value corresponding to Tf (corresponding to the same time), the Ts value is used for weighted calculation to obtain the user's body temperature T and output ; Or, if there is no Ts value corresponding to Tf, the most recent Ts value can be used for weighting calculation.

The previous example is still used for illustration. When the user raises his hand for the first measurement, the processor 110 can receive Tf1 and the Ts value at 12:00, and the processor 110 can obtain the user's single measured body temperature T according to this, and output it. When the user raises his hand for the second time for active measurement, the processor 110 can receive Tf2, but the Ts value is not received at this moment, and the most recent Ts value can be used, that is, the Ts measured at 14:00. Value, to participate in the weighted calculation to get the user's body temperature T.

Or, when the smart watch performs body temperature measurement, the data processing method when actively measuring the body temperature may be different from the data processing method when automatically measuring the body temperature. For example, when the user raises the wrist to actively measure the body temperature, the processor can directly output the received forehead temperature Tf; and when the user automatically measures the user's body temperature while wearing the smart watch, the processor can use the method shown in Figure 22 , After receiving Tf and Ts, get the weighted sum of Tf and Ts, get the body temperature T, and output it.

Through the weighting process, the more accurate measurement data Tf of the infrared thermopile sensor 11 can be used to correct the measurement data Ts of the surface temperature sensor 13, thereby improving the accuracy of the body temperature measurement result.

In another possible embodiment, the first correspondence may be a mapping function. For example, the first correspondence can be expressed as Tf=f(Ts). Therefore, after the processor 110 receives the measured temperature Ts sent by the temperature sensor 13, it takes Ts into the mapping function to obtain the temperature value T corresponding to Ts, and then outputs the temperature value T.

In the embodiment of the present application, the mapping function may be pre-stored in a storage location readable by the processor 110 in advance. Among them, the mapping function may be a preset function in the smart watch. Alternatively, the mapping function may be established by the processor 110 according to a plurality of received measurement data Ts and Tf. For example, in one embodiment, when the number of times the user actively measures body temperature reaches K1 times, such as 20 times, the Tf collected by the infrared thermopile sensor 11 during these 20 measurements and the Ts corresponding to Tf can be used to establish Mapping function. Specifically, when the user actively measures the body temperature, the processor 110 may receive the measured temperatures Tf and Ts, and store the Tf and Ts in a preset storage location. In this way, when the preset storage location has accumulated 20 sets of Tf and Ts data, the processor 110 can perform curve fitting on the relationship between Tf and Ts to obtain the mapping function between the two, and then the The mapping function is stored in another storage location. Wherein, the storage location used to store the measurement data and the storage location used to store the mapping function may be the same or different, which is not limited in this application.

When the processor 110 establishes the mapping function between Tf and Ts, after the mapping function is established, the processor 110 brings the received measurement temperature Ts into the mapping function, and then the body temperature measurement result can be obtained and output. Before the mapping function is established, the temperature sensor and the processor can be implemented at least as follows:

In an embodiment, before the mapping function is established, the surface temperature sensor 13 may measure the temperature Ts according to a preset period or a predetermined time, and transmit the measured temperature Ts to the processor 110. The processor 110 may receive the measured temperature Ts, store the received measured temperature Ts in a preset storage location, and correct the Ts according to the aforementioned weighting function to obtain the body temperature T of the user, and output the body temperature T.

In another embodiment, before the mapping function is established, the surface temperature sensor 13 may measure the temperature Ts according to a preset period or a predetermined time, and transmit the measured temperature Ts to the processor 110. After receiving the measured temperature Ts, the processor 110 stores the measured temperature Ts in a preset storage location. At this time, the processor 110 may temporarily stop calculating the body temperature T until the K1 group of measured temperatures is reached, and the processor 110 may establish a mapping function between Ts and Tf. In this way, when the processor 110 receives Ts again, it can correct the Ts according to the mapping function, and output the corrected Ts, that is, the body temperature T.

In another embodiment, before the mapping function is established, the surface temperature sensor 13 may only collect temperature data Ts when the user is actively measuring, that is, when the infrared thermopile sensor 11 measures the temperature Tf, the surface temperature sensor 13 also measures the temperature Ts. . Therefore, after receiving Ts and Tf, the processor 110 stores the measured temperature Ts in a preset storage location. At this time, the processor 110 may temporarily stop calculating the body temperature T until the K1 group of measured temperatures is reached, and the processor 110 may establish a mapping function between Ts and Tf. At this time, the processor 110 may notify the surface temperature sensor 13 to start working. In this way, the surface temperature sensor can measure Ts periodically or regularly, and after receiving Ts, the processor 110 can correct Ts according to the mapping function and output the body temperature T.

In the embodiment of the present application, when the smart watch is used to realize the automatic measurement of body temperature, the mapping function between Tf and Ts can also be updated. For example, after the mapping function is established, the user takes the initiative to measure body temperature M1 times, such as 30 times, and uses these 30 Tf data and the Ts data corresponding to Tf to re-determine the mapping function between Tf and Ts to realize the mapping Function update. After that, the processor 110 uses the updated mapping function to calculate the body temperature T of the user. Among them, the Ts data corresponding to Tf can be determined in the foregoing manner, and will not be described in detail.

In the embodiment shown in FIG. 22, the smart watch corrects the automatically measured temperature by actively measuring the temperature by the user, which can improve the accuracy of the body temperature measurement result to a certain extent.

In another possible implementation scenario, an infrared thermopile sensor 11 is provided on the front of the smart watch, as shown in Figures 5 to 7, and 14; and the back of the smart watch is also provided with a surface temperature sensor 13, such as 10. As shown in Figure 13-14. In addition, the smart watch can also obtain the ambient temperature Te, or the smart watch is provided with an ambient temperature sensor 12.

At this time, FIG. 23 shows a schematic diagram of a body temperature measurement method in this scenario.

In this scenario, the processor 110 can receive three types of measured temperatures: the forehead temperature Tf, the skin surface temperature Ts, and the ambient temperature Te. At this time, the forehead temperature Tf and the ambient temperature Te can be used to correct Ts.

Therefore, in a possible embodiment, the aforementioned first correspondence between Tf and Ts can be used to obtain the Tf value corresponding to Ts, and then the Tf value (Ts Corresponding Tf value) and the temperature corresponding to the ambient temperature Te, and output it.

In another possible embodiment, the processor 110 may first use the ambient temperature Te to correct the forehead temperature Tf to obtain the corrected forehead temperature, that is, the body temperature Tc at the forehead. For a specific implementation manner, refer to the embodiment shown in FIG. 21 . In this way, the processing 110 may calculate and output the user's body temperature T according to the second correspondence relationship and the received measured temperature, which may include but is not limited to Ts.

Wherein, the second correspondence relationship may be a weighting function. For example, the second correspondence can be expressed as: T=w3*Tc+w4*Ts, where w3 and w4 are preset weights, and the sum of w3 and w4 can be 1, and the application does not limit the specific weight value. Or; the second correspondence can be a mapping function. For example, the second correspondence can be expressed as: Tc=f(Ts).

The second correspondence relationship may be pre-stored in the readable storage location of the processor 110 in advance.

In addition, when the second correspondence is a mapping function, it may also be established by the processor 110. For example, the processor 110 establishes a mapping function between Tc and Ts according to K2 sets of measurement data (Tf, Te, and Ts) accumulated in another storage location. Before establishing the mapping function between Tc and Ts, the ambient temperature sensor 12 and the surface temperature sensor 13 can work normally, or only measure the temperature when the user is actively measuring. The processor 110 can receive the measurement data, store it in a preset storage location, and establish a mapping function. Before the mapping function is established, the processor 110 may not perform the operation of calculating the user's body temperature T, or the processor 110 may calculate and record the user's body temperature T according to the aforementioned weighting function; and after the mapping function is established, the processor 110 Bring the received measured temperature into the mapping function to calculate the user's body temperature T and output it. Here, reference may be made to the description shown in FIG. 22, and the description is not repeated.

And, when the second correspondence is the mapping function, when the number of active measurements by the user reaches M2 times, the processor 110 may also use the measurement data stored in the preset storage location to perform the mapping function between Tc and Ts. Update, so that the second correspondence is closer to the user's recent body temperature state, which is beneficial to improve the measurement accuracy of body temperature T.

In another possible implementation scenario, an infrared thermopile sensor 11 is provided on the front of the smart watch, as shown in Figures 5 to 7, and 14; and a heat flux sensor 14 is also provided on the back of the smart watch. At this time, the heat flux sensor 14 can measure and output the deep skin temperature Td, as shown in Figs. 12 to 14 for example.

At this time, FIG. 24 shows a schematic diagram of a body temperature measurement method in this scenario.

In this scenario, the processor 110 can receive two types of measured temperatures: the forehead temperature Tf and the skin deep temperature Td. Thus, the processor 110 can use the third corresponding relationship between the forehead temperature Tf and the deep skin temperature Td, and the received measurement temperature (which may include but is not limited to Td), to calculate and output the user's body temperature T.

Wherein, the third correspondence relationship may be a weighting function. For example, the third correspondence can be expressed as: T=w5*Tf+w6*Td, where w5 and w6 are preset weights, and the sum of w5 and w6 can be 1, and the application does not limit the specific weight value. Or; the third correspondence can be a mapping function. For example, the third correspondence can be expressed as: Tf=f(Td).

The third correspondence relationship may be pre-stored in the readable storage location of the processor 110 in advance.

In addition, when the third correspondence is a mapping function, it may also be established by the processor 110. For example, the processor 110 establishes a mapping function between Tf and Td according to K3 sets of measurement data (Tf and Td) accumulated in another storage location. Before establishing the mapping function between Tf and Td, the heat flux sensor 14 can work normally, or only measure the temperature when the user is actively measuring. The processor 110 receives the measurement data, stores it in a preset storage location, and establishes a mapping function. Before establishing the mapping function, the processor 110 may suspend the calculation of the user's body temperature T, or calculate and record the user's body temperature T according to the aforementioned weighting function; and after the establishment of the mapping function, the processor 110 may bring the received measurement temperature into the Mapping function to calculate the user's body temperature T and output it. Here, reference may be made to the description shown in FIG. 22, and the description is not repeated.

And, when the third correspondence is the mapping function, when the number of active measurements by the user reaches M3 times, the processor 110 may also use the measurement data stored in the preset storage location to perform the mapping function between Tf and Td. Update, so that the third correspondence is closer to the user's recent body temperature state, which is beneficial to improve the measurement accuracy of the body temperature T.

In another possible implementation scenario, an infrared thermopile sensor 11 is provided on the front of the smart watch, as shown in Figs. 5-7 and 14; and the back of the smart watch is also provided with a heat flux sensor 14, such as Shown in Figure 12 to Figure 14. In addition, the smart watch can also obtain the ambient temperature Te, or the smart watch is provided with an ambient temperature sensor 12.

In a possible embodiment, the smart watch uses the heat flux sensor 14 to measure the deep skin temperature Td of the user. At this time, FIG. 25 shows a schematic diagram of a body temperature measurement method in this scenario.

In this scenario, the processor 110 can receive two types of measured temperatures: the forehead temperature Tf, the ambient temperature Te, and the deep skin temperature Td. At this time, the forehead temperature Tf and the ambient temperature Te can be used to correct the deep skin temperature Td.

Therefore, in a possible embodiment, the aforementioned third correspondence between Tf and Td can be used to obtain the Tf value corresponding to Td, and then the Tf value (Td Corresponding Tf value) and the temperature corresponding to the ambient temperature Te, and output it.

In another possible embodiment, the ambient temperature Te may be used to correct the forehead temperature Tf to obtain the body temperature Tc at the forehead. For a specific implementation manner, refer to the embodiment shown in FIG. 21. Thus, the processor 110 may use the fourth correspondence between the body temperature Tc at the forehead and the deep skin temperature Td, and the received measurement temperature, which may include but is not limited to Td, to calculate and output the user's body temperature T.

In another possible embodiment, if the heat flux sensor 14 is used to measure the heat flux HF, a surface temperature sensor 13 may also be provided in the smart watch, as shown in FIG. 14. At this time, refer to the schematic diagram of the body temperature measurement method shown in FIG. 26. As shown in FIG. 26, the processor 110 may receive HF and Ts, and calculate the user's deep skin temperature Td from this. In this way, the processor 110 uses the ambient temperature Te to correct the forehead temperature Tf to obtain the body temperature Tc on the forehead. For a specific implementation manner, refer to the embodiment shown in FIG. 21. Furthermore, the processor 110 may establish a fourth correspondence between Tc and Td according to the received measurement function.

Wherein, the fourth corresponding relationship may be a weighting function. For example, the fourth correspondence can be expressed as: T=w7*Tc+w8*Td, where w7 and w8 are preset weights, and the sum of w7 and w8 can be 1, and the application does not limit the specific weight value. Or; the fourth correspondence can be a mapping function. For example, the fourth correspondence can be expressed as: Tc=f(Td).

The fourth correspondence may be pre-stored in a storage location readable by the processor 110 in advance.

In addition, when the fourth correspondence is a mapping function, it may also be established by the processor 110. For example, the processor 110 establishes a mapping function between Tc and Td according to K4 sets of measurement data (Tf, Te, and Td; or Tf, Te, Ts, and HF) accumulated in another storage location. Before the mapping function between Tc and Td is established, the heat flux sensor 14 can work normally, or only measure the temperature when the user is actively measuring. The processor 110 can receive the measurement data, store it in a preset storage location, and establish a mapping function. Before establishing the mapping function, the processor 110 may suspend the calculation of the user's body temperature T, or calculate and record the user's body temperature T according to the aforementioned weighting function; and after the establishment of the mapping function, the processor 110 may bring the received measurement temperature into the Mapping function to calculate the user's body temperature T and output it. Here, reference may be made to the description shown in FIG. 22, and the description is not repeated.

And, when the fourth correspondence is the mapping function, when the number of active measurements by the user reaches M4 times, the processor 110 may also use the measurement data stored in the preset storage location to perform the mapping function between Tc and Td. Update to make the fourth corresponding relationship closer to the user's recent body temperature state, which is beneficial to improve the measurement accuracy of body temperature T.

In the embodiment shown in Figures 24 to 26, the heat flux sensor 14 can work after multiple active measurements, which reserves time for the heat flux sensor 14 to reach thermal equilibrium, which is conducive to obtaining a higher precision Td (or HF). Furthermore, in the embodiment of the present application, taking the example shown in FIG. 26 as an example, the processor 110 may correct Td according to the weighting function before reaching K4 active measurements, which also guarantees the accuracy of the body temperature measurement result to a certain extent.

In addition, in the foregoing embodiments, any two values of K1 to K4 are the same or different; any two of M1 to M4 have the same or different values, which is not limited by this application.

It should be noted that, in the embodiment of the present application, the temperature sensor 11 can also measure temperature data of other parts of the human body. For example, the temperature sensor 11 can also be used to measure tympanic membrane temperature, oral cavity temperature, underarm temperature, and the like. In the foregoing embodiments shown in FIGS. 20 to 26, the temperature sensor 11 is used to measure the temperature of the forehead, which is a specific embodiment and should not limit the technical solution of the present application. Based on this, when the temperature sensor 11 is used to measure different temperatures, the corresponding relationships adopted in the foregoing embodiments may be different.

For example, in the embodiment shown in FIG. 21, if the user raises the wrist to measure the ear canal temperature at the ear (assumed to be recorded as Tr), the temperature sensor 11 transmits the measured ear canal temperature Tr to the processor 110, and the processor 110 110 After receiving the ear canal temperature Tr and the ambient temperature Te, the corresponding table between Tr, Te and Ta (representing the eardrum temperature) can be used to calculate the eardrum temperature Ta and output the eardrum temperature Ta. Thus, in the smart watch or Ta is displayed on the phone.

For another example, in the embodiment shown in FIG. 24, the user can also raise the wrist to measure the temperature under the armpit (assuming it is recorded as Tu), then when the smart watch performs automatic measurement, the processor 110 receives the measured temperature Tu under the armpit. After the skin deep layer temperature Td, the user's body temperature T can be calculated and output according to the corresponding relationship between Tu and Td. For example, the processor 110 may calculate the weighted sum between Tu and Td (the sum of weights may be 1), and output the weighted sum; for another example, the processor 110 may calculate the weighted sum between Tu and Td according to a preset or pre-established value. Mapping function between to obtain the temperature value corresponding to Td, and output the temperature value corresponding to Td.

For another example, in the embodiment shown in FIG. 25, the user can also raise the wrist to measure the temperature of the underarm (assumed to be denoted as Tu). In this way, after the processor 110 receives the underarm measured temperature Tu and the ambient temperature Te, The method shown in Figure 22 can be used to calibrate Tu with Te to obtain the corrected underarm temperature Tv. Therefore, when the smart watch performs automatic measurement, the underarm temperature Tv and the deep skin temperature Td can be weighted. Function or mapping function to calculate the user's body temperature T and output it.

Not exhaustively.

In this way, the smart watch can use the camera to determine the currently measured body part. In one embodiment, please refer to FIG. 27. FIG. 27 shows the front structure of another smart watch. A camera 16 is provided on the front of the smart watch, and the camera 16 can be used to collect images or videos. Specifically, when the user raises the wrist, the camera starts to work; or, when the temperature sensor 11 works, the camera starts to work. The camera and the temperature sensor 11 can communicate directly or indirectly through the processor 110. In this way, after the image or video collected by the camera is output to the processor 110, the processor 110 can perform image recognition on it to determine the human body part facing the front of the smart watch. Furthermore, the processor 110 of the smart watch may adopt the corresponding relationship of the human body part to determine the body temperature of the user, and output it to the display screen 15 or the mobile phone 200.

It can be understood that the embodiment shown in FIG. 27 is schematic. In an actual scenario, the camera 16 may be set in any of the embodiments shown in FIGS. 5-7 and 10-14.

Or, in a smart watch or a mobile phone, options for different body parts can also be set. Thus, in an actual scenario, the smart watch can adopt different correspondences according to the user's selection to determine the user's body temperature. Exemplarily, FIG. 28 shows a schematic diagram of another human-computer interaction scenario. As shown in Figure 28, on the a interface, the user can click on a smart watch currently connected to enter the smart watch's setting interface (b interface). On the b interface, the user can click on the control 219 (the control 219 is used to provide the user with the function of selecting a body temperature measurement site), so that the mobile phone jumps to the c interface. On the c interface, the user is prompted: "When you raise your wrist, the part of the human body that the smartwatch is facing is the temperature measurement part. If you do not select it, the default forehead is the temperature measurement part. You can click here Modify the body temperature measurement part at the same time.” And, on this interface, a number of different body parts and the switch controls for each part are also displayed. For example, the switch control 220 for the forehead and the switch control 221 for the ears. On the c interface, the switch control 220 is in the on state, and it is assumed that the temperature of the forehead is measured when the user raises the wrist. The smart watch can use the corresponding relationships corresponding to the forehead temperature to implement the foregoing solution and obtain the user's body temperature.
